BOX-STRAPPING MACHINE.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed March 23, 1914. Serial No. 826,530.

To all whom it may concern Be it known that we, JESSE E. GoDLEY and JoI-IN M. CARROLL, citizens of the United States, residing at Vallejo, inthe county of Solano and. State of California, have invented new anduseful Improvements in Box-Strapping Machines, of which the following isa specification.

This invention relates to improvements in box strapping machines.

The objects of the invention are, first, to provide a simple,substantial, easily operated machine which is so constructed that it maybe quickly adjusted to handle boxes of various lengths and diameters,and second,

to provide means for applying bands to the boxes under high tension andperfect alinement.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings in which Figure 1 is a plan viewof the machine. Fig. 2 is a longitudinal, vertical section on line 2-2,Fig. 1. Fig. 3 is a cross section on line 33, Fig. 2. Fig. 4: is a crosssection on line 47-41, Fig. 2. Fig. 5 .is a perspective of theband-gripping mechanism.

Referring to the drawings, A indicates the main frame of the machine inwhich the several parts of the box strapping mechanism are mounted.

B indicates a box supporting frame, and 2 a pair of standards on theupper ends of which are journaled a pair of band or strapcarrying reels8. The box supporting frame is here shown as consisting of a base-plate4:, mounted upon timbers 5, carried by a pair of cross-frames 6,extending between the sides of the main frame A, and adjustablysupported in same as indicated at 7. The outer end of the base-plate 1is slotted as indicated at 8, for the purpose of permitting theadjustment of a pair of end brackets 9. These are secured in theiradjusted position by any suitable means, or as here shown by bolts 10.The brackets 9 are engageable with the ends of the box, as indicated at11, and are provided for the purpose of holding these in alinement withthe several parts of the box strapplng mechanism. The box is furtherheld in position by a standard 12, suitably secured as at 13 to thesupporting timber of the base-plate. The vertical adjustment of thebase-plate permitted by the slotted cross-frames 6, permits the frame tobe raised or lowered to handle boxes of different diameters, and the adustment of the crosswise frame of brackets 9 permits boxes of variouslengths to be handled.

11 indicates a shaft which is journaled as at 15 in boxes supported onthe upper side of the main supporting frame. Suitably secured to saidshaft is a pair of upwardly extending arms 16, upon the upper ends ofwhich are formed sleeve extensions 17. On the outer ends of said sleeveextensions are formed a pair of vertically disposed lugs 18 andsupplementary lugs 19. Suitably secured between said lugs is a pivot pin20, one end of which is suficiently extended to form a support for aspring 21. Pivotally mounted on pins 20, between the lugs 18 are a pairof strap grips 22. The upper ends of said strap grips are connected by across-bar 23, and the rocking movement of the grips is limited by bars21 extending between supplementary lugs 19. Springs 21 carried by theinner projections of pins 20 are engageable at one end with sleeveextensions 17 and the upper ends with crossbar 23, and are provided forthe purpose of normally holding the strap-gripping members in engagementwith stop-bars 24:. The lower ends of the strap-gripping members arecam-shaped as indicated at 25, and are so positioned as to becomeengageable with a pair of shoes 26 carried on sleeves 17 between thevertical lugs 18. Arms 16 are secured to shaft 14 by screws 1 1 and aretherefore adapted to be moved inwardly or nownwardly on said shaft withrelation to the center of the machine. The cross-bar 23 extendingthrough the upper ends of the strap-gripping members is similarlysecured by said screws 23, and the second cross-bar 27 extending throughthe sleeves 17 on the upper ends of arms 16 is also secured in thismanner by screws 17. The adjustable mounting of the arms with connectedparts permits these to be extended'or contracted as the case may be, forthe purpose of strapping boxes of different lengths.

Standards 2 upon which the strap carrying reels 3 are mounted areadjustably secured to the main frame. Thisis accomplished by providing apair of dove-tailed in Fig. 2.

guide members 28, having slots 29 formed therein. The base portion ofthe standards is grooved to engage the dove tailed slots and are securedthereto by bolts 30, which are adapted to extend through slots 29,formed,

in the dove-tailed extensions previously de-, scribed. 7

Thewhole mechanism so far described is operated through the mediumof afoottreadle which consists of a pai r of arms 31,

pivotally mounted on the cross shaft 32.

The outer ends ofs'aid' arms are connected by a foot-board33, andextending across the arms upon brackets 34 is a crossbar 35. Suitablysecured to said cross-bar isafiexiblecable 36 which passesthrough theguide sheave 37,]the other end of said cablebeingsecured as at 38 toapproxi mately the center ofcross-bar 23. The-foot readle is no mallyheld in the elevatedposition indicated in Fig. 2 by reason of a coilspring39 and arms 16 upon which the strapgripping mechanism is normallyheld in the full line position indicated in Fig.

2, by means of a coil spring 40 which is at tachedat one end to the mainarm and at the other to a downwardly extending arm 41, secured as at 42.to shaft 14. E

- 1V 7 The operation'of the device will'be' as fol- ,lows: The box to bestrapped is first" placed upon'the base-plate 4. The side brackets 9 arethenadjusted so as to 'engagewith the ends of 'the box indicated in Fig.1Q The base-plate4 is then either elevated or lowered as'the case may bethrough the adjusting'mechanism, indicated at 7 until the top of'the boxisslightly above the position of the strap-gripping mechanism, asindicated straps, and thisisaccomplished as follows: The ends ofthestraps are first unwound from the reels 3 and passed through theverpressingthe treadle lever31. Movement is transmitted when treadle '31is depressed I through cable 36t0 bar 38; and dueto the bar 38 beingconnected with the strap-grip: ping members same will cause the parts torock into the dotted line position indicated at 44, and cause thecamends of same to move into gripping engagement with the straps 45which pass over shoes 26. i' A further depression of the foot-treadlewill then cause-bar 38, with connected strap-gripping members, togetherwith lever 16, to move into the dotted line position, indicated at46;

the strap being secured'between the cam ends The box thus adjusted inposition, is then ready for the application ofth'e 25 of the grippingmembers and the shoe 26 y will thus be drawn taut over the edge of thebox, and may then be nailed to the box- The V foot-treadle 31 is now'released, permitting spring 39. to return the treadle to the normalelevated position, giving the cable sufiicient slack to permit spring 40to return arms 16 to normal position, and also permitting f springs2lto"rock bar 23 with connected gripping members into released position,

The box is then turned'over in thej'direction of arrowf a topresent a'new 'side'toibe strapped. The cycle of operation; that is,"

that of depressingthe foot-lever, again rocks. V

the gripping 'members "into gripping po'si' tion, and draws'thestrapstaut over the edge of the boxij The moment'the straps "havebeen drawn taut the straps are nailed tozthe box," the foot-lev'erfisthen raised and thebox is again turned. These operations are re-' peateduntil the strap. has become entirely wound around the" box, when theymay be severed andfthe box removed. Y The machine construction. as hereshown relieves the operator of the necessity of tightening the straps byliand.. simply pressingthe foot lever the straps-are drawn much tighterthan could be otherwise done. The operator isthus'free' to use bothhands for the purpose of nailingZthe strap when this isin tautcondition. The adjustable mounting of the severalparts, together withthe guiding; of the strap iron, insures: per

fect alinem'ent of the-"straps upon the endsof the box; The nailsbywhich the straps are secured will thusi always enter the end sec.- tionsof the box, orinotherwords, prevent nails fromentering'theinterioroffthe box wh'ere they might damageithe goodscontained therein, or anylining with whichthegoods might be inclosed.

The machine is slmple ndcompact in con struction, and can be operatedzfany per son. It may furthermore be adjustedlto handle practically anysize' box' and the alinement'of the strap iron produce anet ofuniformres'ult.

The materials and finish' of the 'se veral parts of the invention may besuch as the of the 'manufac{ judgment and experience turer may dictate.L

Having thus described ourinventiomwhat we claim an'cl desrre to secure'by Letters Patent is f s 1 1. In a, box-strapping machin'eyin-"combi'nation, with strap-woundzreels,a vertically disposed carrier having apair of piv:

'oted arms, spring means to tension the arms, a cross bar connecting thearms,'ashoe on each arm, a vertical-strap grip pivoted to ea'ch'armilllCll'litVll'lg a cam on its lower end springs connected to the gripsand to. the respective arms to. normallyvhold the cams of the grips awayfrom the shoes, across-bar which cooperates with the shoe of the'arm,

connecting the upper ends of the grips, a treadle, and a cable connectedto the crossbar of the grips and movably engaged with a stationary pointto the rear of the arms and connected to the treadle.

2. In a box-strapping machine, in combination, with a box support andstrapwound reels, a vertically disposed carrier swingable at its upperend toward and away from the box, rigid jaws on the carrier, verticallydisposed spring tensioned jaws pivoted to the carrier and having theirlower ends for cooperation with the rigid jaws to grip the strapstherebetween, means connect ing the pivoted jaws to effect movement ofsame in unison, and means connected to said connecting means of thepivoted jaws for moving the pivoted jaws to gripping position and forsimultaneously swinging the carrier horizontally to draw the strapstaut.

8. In a box-strapping machine, in combination, with a box support andstrapwound reels, a vertically disposed spring tensioned carrierswingable at its upper end toward and away from the box, and located onthe rear side of the box support, rigid jaws on the carrier, verticallydisposed spring tensioned jaws pivoted to the carrier and having theirlower ends for cooperation with the rigid jaws to grip the strapstherebetween, means connecting the pivoted jaws to effect movement ofsame in unison, a cable connected to said connecting means of thepivoted jaws for moving the pivoted jaws to gripping position and forsimultaneously swinging the carrier horizontally to draw the strapstaut, and means operable from the front side of the boX support toactuate the cable.

In testimony whereof we have hereunto set our hands in the presence oftwo sub scribing witnesses.
